Sarcoidosis: What is it? Why does it occur? Are there any potential environmental triggers? Our guest, Dr. Adam Morgenthau, sheds light on these and more, including making the diagnosis of sarcoidosis, the need for imaging or biopsy and how it will distinguish between organ involvement and organ damage. And, perhaps just as important, we discuss when to treat it, including the various medications that can be effective for organ system manifestations. Finally, we conclude with a discussion on the latest research into Sarcoidosis patients, and their families, living with this disease.
